IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 126,463, dated May 7,1872.

Specification describing anew and Improved VVashing-Machine, invented byWLLLIAM G. KNOWLES, of Jamestown, in the county of Newport and State ofRhode Island.

Figure 1 represents a vertical longitudinal section of my improvedwashing machine. Fig. 2 is a vertical transverse section of the same onthe line o c, Fig. 1.

Similar letters of reference indicate corresponding parts. Y

This invention relates to a new washing-machine in which a reciprocatingslotted washboard is arranged to move on spring-rails under and againstfriction-rollers that hang in a spring-frame, all as hereinafter morefully dcscribed.

Ain the drawing represents the suds-box of the washing-machine. B is theoperating crank-shaft hung i-n the upper part of the sudsbox, near oneend of same. Its cranks are, by means of rods a a, connected with arecipro- .eatin g frame, C, on which a slotted wash-board,

b, is secured. rllhe frame C rests on inclined rails d d, whose upperends are pivoted at e to the sides of the suds-box, while their lowerends are suspended on springs j. Above the reciprocating frame C ispivoted, at g, to the sides of the suds-box a frame, D, in which aseries of rollers, k h, are hung, springs z' drawing the frame D down onthe wash-board. The articles to be cleaned are, through a space betweentwo of the rollers h, interposed between the wsah-board b and saidrollers, and the crankshaft next turned with suitable rapidity. Thiswill cause the board to rub against the rollers h and to act on thegoods in the manner necessary to effect the desired cleaning process.Adjustable stops jj on the inner sides of the suds-box serve to supportthe frame D and to prevent it from applying too much pressure ou certaingoods. The goods pass down through the slot in the wash-board into thesuds, and are drawn through the washing apparat-us by the frictionexerted against the rollers by the reciprocating wash-boards.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The reciprocating frame C, carrying the slottedwash-boardb and combined with the springrails d d and with theadjustable roller-frame D, substantially as herein shown and described.

WILLIAM G. KNOWLES.
